Add the mixture to a spray bottle, shake like crazy and then spray around windows, doors, air ducts and anywhere else you think spiders may be entering your home. Another thing you can do if you have lots of air vents or holes in your walls/floors is to soak some cotton balls in the mixture, and place them in the ducts and holes etc.

If you do this once a week, you’ll notice a dramatic reduction in the numbers of spiders entering your home.
